Due to the increase in population, the demand for water has also risen over a period of time. The area with sufficient rainfall is also facing scarcity of water due to improper water storage management. In order to overcome the scarcity of water, vented dams are constructed to harvest the water. The present study is attempted for two vented dams that are at Nethravathi River and Papanashini River. In order to increase the storage of water in the reservoir the height of the dam gate is increased by 2 m on the existing height. Due to which there is submergence of land and there is increase in area of storage. Bathymetry survey is carried out to determine the depth of water stored and volume is estimated. The water stored can be used for irrigation, surrounding agricultural purposes. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.BathymetryWater storage management
